A reactor system for thermally treating a hydrocarbon-containing stream includes a pressure containment vessel having an interior chamber defined by a first end, a second end, and at least one sidewall extending from the first end to the second end. A heat transfer medium converts electrical current to heat is positioned within the interior chamber of the pressure containment vessel, and the heat transfer medium has a first end face, a second end face, and channels extending between the first end face and the second end face. A heat sink reservoir includes molten salt, and at least one of a heater or heat exchanger is fluidly coupled to the heat transfer medium and thermally coupled to the heat sink reservoir.

A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.

A reactor for efficient control of endothermic and exothermic catalytic reactions, including, for example, Fischer Tropsch reactions. Also disclosed are methods of delivering coolant materials and gasification source materials to the reactor.

Provided is a bubble column reactor including a reaction zone configured to carry out a reaction of a gaseous reactant in a liquid reaction medium; a disengaging section provided above the reaction zone and configured such that a first gas stream rising from the reaction zone is introduced into the disengaging section; and a condensation zone provided above the disengaging section and configured such that a second gas stream rising from the disengaging section is introduced into the condensation zone, wherein a diameter of the condensation zone is greater than a diameter of the disengaging section.

A chemical reactor for use in a chemical process wherein a reactant and/or a target product is prone to produce undesirable byproducts through secondary reactions. The reactor is configured with a first flow passage for passing a flow of an overly reactive reactant; a permeable first wall for controlled flow of the overly reactive reactant into a second flow passage providing a flow of a second reactant; a permeable second wall having a catalyst supported on an inner surface thereof for catalyzing reaction of the reactants flowing in the second flow passage; the permeable second wall passing through a flow containing the target product; and a non-permeable third wall defining a third flow passage for exiting the product mixture. The reactor can be employed in selective oxidation, oxidative dehydrogenation, and alkylation processes to reduce the formation of byproducts.
